With just under four minutes to go in the first quarter of A&M's game with Missouri, freshman quarterback Johnny Manziel rolled to the left and took off on one of his signature scrambles, but Missouri cornerback E.J. Gaines latched onto his left leg and Manziel fell awkwardly. He rolled around on the ground clutching his left knee while A&M medical personnel tended to him.

Fans at Kyle Field initially went silent, eventually breaking into a chant of "Johnny! Johnny!" while the quarterback was still down.

After a few minutes on the field, Manziel popped up and walked off the field on his own power, while backup Jameill Showers came in for the next play, a 38-yard touchdown run by Christine Michael.

Showers remained at quarterback for the start of Texas A&M's next drive, but Manziel returned for the start of the second quarter.
